The list head is left pointing at freed kmalloc-96 objects.</p> <p>A second AMDKFD_IOC_CRIU_OP from the same process re-enters: list_empty() reads the dangling -&gt;next (use-after-free), the loop walks freed entries, and each is kfree()&#39;d again (double-free). This is reachable by an unprivileged render-group user via /dev/kfd with no capabilities required.</p> <p>Add list_del() before the kfree() so the list is properly emptied. The list_for_each_entry_safe() iterator already caches the next pointer, so unlinking during the walk is safe.</p> <p>(cherry picked from commit 6322d278a298e2c1430b9d2697743d3a04b788b1)</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>drm/amdkfd: fix list_del corruption in kfd_criu_resume_svm</p> <p>The cleanup tail of kfd_criu_resume_svm() walks svms-&gt;criu_svm_metadata_list and kfree()s each struct criu_svm_metadata without removing it from the list.
